We divide 81087960 by 978
The aim is to understand the frequency of 978 in 81087960.

Going ahead to step 1:
When dividing 8 by 978, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 978

Going ahead to step 2:
When dividing 81 by 978, we get 0 with a remainder of 81.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 81 to get 81.
Take the next digit (0) from the dividend and append it to 81, then repeat: 810 / 978

Moving on to step 3:
978 goes into 810 0 times with a remainder of 810.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 810 after subtracting 0 from 810.
Bring next digit (8) of the dividend behind the 810 and repeat the process: 8108 / 978

Going ahead to step 4:
978 can be fit into 8108 8 times, resulting in a remainder of 284.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we take 7824 away from 8108, we end up with 284.
Append the next digit (7) from the dividend to 284 and continue with: 2847 / 978

Going ahead to step 5:
The number 978 fits into 2847 2 times, leaving a remainder of 891.
The next digit of our result is 2. 
Result so far: 82.0
If we subtract 1956 from 2847, we get 891.
Grab the next digit (9) from the dividend, add it to 891, then carry on: 8919 / 978

Let's proceed to step 6:
978 can be fit into 8919 9 times, resulting in a remainder of 117.
Record the quotient 9 as the next digit in the result. 
Result so far: 829.0
If we take 8802 away from 8919, we end up with 117.
Fetch the next digit (6) from the dividend, attach it to 117 and continue: 1176 / 978

On to step 7:
1176 divided by 978 is 1 with a remainder of 198.
Use 1 as the next digit of our solution. 
Result so far: 8291.0
If we subtract 978 from 1176, we get 198.
Take the next digit (0) from the dividend and append it to 198, then repeat: 1980 / 978

Let's proceed to step 8:
978 goes into 1980 2 times with a remainder of 24.
The next digit of our result is 2. 
Result so far: 82912.0
The remainder is 24 after subtracting 1956 from 1980.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 9:
If we divide 240 by 978, we get 0 and a remainder of 240.
Put 0 as the next digit of the answer. 
Result so far: 82912.0
If we subtract 0 from 240, we get 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Advancing to step 10:
978 goes into 2400 2 times with a remainder of 444.
Use 2 as the next digit of our solution. 
Result so far: 82912.02
If we subtract 1956 from 2400, we get 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

Step 11:
If we divide 4440 by 978, we get 4 and a remainder of 528.
Record the quotient 4 as the next digit in the result. 
Result so far: 82912.024
Subtracting 3912 from 4440 leaves us with 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Moving on to step 12:
The number 978 fits into 5280 5 times, leaving a remainder of 390.
Use 5 as the next digit of our solution. 
Result so far: 82912.0245
The remainder is 390 after subtracting 4890 from 5280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3900, and continue the process.

Moving on to step 13:
3900 divided by 978 is 3 with a remainder of 966.
Put 3 as the next digit of the answer. 
Result so far: 82912.02453
Subtract 2934 from 3900 to get 966.
Since there are no more digits in the dividend, we add a zero to the remainder making it 9660, and continue the process.

Step 14:
978 goes into 9660 9 times with a remainder of 858.
The number 9 becomes the next digit in our result. 
Result so far: 82912.024539
Subtracting 8802 from 9660 leaves us with 858.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8580, and continue the process.

Step 15:
978 can be fit into 8580 8 times, resulting in a remainder of 756.
The next digit of our result is 8. 
Result so far: 82912.0245398
Subtract 7824 from 8580 to get 756.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7560, and continue the process.

Let's proceed to step 16:
978 can be fit into 7560 7 times, resulting in a remainder of 714.
The number 7 becomes the next digit in our result. 
Result so far: 82912.02453987
The remainder is 714 after subtracting 6846 from 7560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7140, and continue the process.

The quotient of the division is 82912.02453987, and the remainder is 7.14e-07.
